ABSTRACT

In one aspect, a heat not burn electronic cigarette device may include a cap comprising a fixer and a mouthpiece; an air tube coupled to the cap; a connector coupled to the air tube; said connector having an opening and a connector cap removably covering the opening; a heating tube coupled to the connector; and a cigarette unit inserted into the heating tube, wherein cigarette smoke is generated from the cigarette unit when heated by the heating tube, and the cigarette smoke can then pass through an airway including the connector, the air tube, the fixer and the mouthpiece. In one embodiment, a diameter of the opening is ½ to ⅓ of a height of the connector.

FIELD OF THE INVENTION

The present application generally relates to electronic cigarettes, and more particularly, to a heat not burn electronic cigarette device, or a non-combusted cigarette device.

BACKGROUND OF THE INVENTION

Most of the heat-not-burn electronic cigarette devices, or non-combusted cigarette device have the opened airway. Users would have to take off either the top cap or the bottom cap to do their maintenance when a cigarette is broken inside the device, or their is heavy carbon build-up on the heating component. The opening is usually on the opposite end of the cigarette inlet. Although the above structure is a simple orientation, there are still some disadvantages:

The opening is at top: in most of heat not burn electronic cigarette devices, the opening is at the top. However, the tobacco or carbon would gather around the opening and forms liquid drops. In addition, the sealing could be easy to leak since the hot vapor rises vertically. Once the sealing is loose, vapor and liquid will permeate out of the airway, causing damage to electronic components.

The opening is at bottom: it means that the cigarette is inserted from the top. However, users may have to either use the cigarette filter as mouth-piece since the cigarette filters are proved as not being capable of standing the temperature of heat-not-burn process, or cut the filter off every time when they insert the cigarette, which is not a user-friendly using experience.

The openings are at both top and bottom: in this case, the openable components are too close to the heating components. In the long term, high temperature may make the parts aging faster, increasing the possibility of deformation or break. Therefore, there is still a need for a heat not burn electronic cigarette device to provide an improved quality and solve the problem caused from the top and/or bottom opening.
